Consultant - Software Engineer

Experience: 10+ years

---

Role Overview

We are seeking a Consultant Software Engineer with Java as the primary skill and AWS as secondary to architect and deliver scalable, secure, and resilient cloud-native platforms. This is a hands-on technical role covering design, implementation, performance, security, and observability—combined with technical mentorship, accountability for outcomes, and clear stakeholder communication.

Key Responsibilities

· Architecture & Solution Design: Translate business and NFRs into robust service, data, and integration designs, document decisions (ADRs), define API contracts and versioning strategies.

· Build & Delivery: Implement Java/Spring Boot microservices and REST APIs, design event-driven integrations, ensure backward compatibility and operational readiness.

· Cloud Engineering (AWS): Select and apply the right AWS services/patterns (serverless vs. containers) for scale, reliability, security, and cost efficiency.

· Quality Engineering: Establish test strategies (unit, integration, contract, performance), enable shift-left quality with CI quality gates and automated pipelines.

· Performance & Resilience: Profile JVM and databases, tune queries and memory, apply resilience patterns (circuit breakers, retries, bulkheads) and effective caching.

· Security & Compliance: Implement secure coding, OAuth2/JWT, secrets management, encryption, align to policy/regulatory requirements and support risk remediation.

· Observability & Operability: Implement logs/metrics/traces, define SLIs/SLOs, actionable alerts, dashboards, drive incident readiness and RCAs.

· Cost Optimization: Right-size resources, design efficient data access patterns, and apply autoscaling, lifecycle policies, and caching/CDN strategies.

· Stakeholder Communication: Communicate options, trade-offs, risks, and delivery plans clearly with Product, Architecture, Security, and SRE.

· Technical Mentorship: Mentor engineers via pairing, code/design reviews, and knowledge shares, contribute reusable libraries, templates, and IaC modules.

· Facilitate agile ceremonies : (stand-ups, backlog refinement, sprint planning, demos, retros) with a focus on technical outcomes, risk surfacing, and sprint goal clarity.

· Refine stories into actionable technical tasks: ensure Definition of Ready/Done, unambiguous acceptance criteria, testability, and accurate story point estimation.

· Security: OWASP Top 10, dependency scanning, SBOM awareness.

AWS (Secondary )

· Core Services: Lambda, API Gateway, S3, DynamoDB, RDS/Aurora, EventBridge, SQS, SNS, ECS/Fargate, monitoring with CloudWatch/X-Ray, auditing with CloudTrail.

· Security & Networking: IAM (least privilege), KMS encryption, VPC (subnets, SGs/NACLs), Secrets Manager/Parameter Store, basic WAF.

· Infrastructure as Code: AWS CDK (TypeScript preferred) or Terraform/CloudFormation, environment promotion and GitOps-friendly workflows.

· Reliability & Cost: Autoscaling, throttling, DLQs, retries/backoff, cost-aware designs (right-sizing, storage tiers, capacity models for DynamoDB).

· Deployment Patterns: Blue/green, canary, feature flags, zero-downtime deployments.
